You won't find any hobby stores selling Select products. Since 2004, Select decided to sell their product through retail only - cutting out the hobby market all together. Bad, bad mistake if you ask me. so you'll only find Select in newsagents and maybe a post office or k-mart/target.
That's it. We had a group buy where the cost price was given and even that was $82.50 or more. Count in eBay fees etc, I doubt anyone would sell it below $80.
